How is ytterbium 169 made?
How is ytterbium 169 made?
This compound is prepared by chelating trivalent ytterbium 169, an isotope of one of the rare earth elements, with diethylenetriaminepentaacetic acid (DTPA). Ytterbium 169 has a physical half-life of thirty-two days and emits primarily gamma rays (8-308 keV).
How is ytterbium produced?
Ytterbium is produced from its ores by reaction with lanthanum metal. For example, the element is extracted by solvent extraction and ion exchange from monazite.
Where is ytterbium commonly found?
Ytterbium is found with other rare-earth elements in several rare minerals. It is most often recovered commercially from monazite sand (0.03% ytterbium). The element is also found in euxenite and xenotime. The main mining areas are China, the United States, Brazil, India, Sri Lanka, and Australia.
What is the origin of the element ytterbium?
Ytterbium was isolated in 1878 by Jean Charles Galissard de Marignac at the University of Geneva. The story began with yttrium, discovered in 1794, which was contaminated with other rare-earth elements (aka lanthanoids)….

What element has the atomic number of 169?
Please visit the Ytterbium element page for information specific to the chemical element of the periodic table.
How is ytterbium used?
Ytterbium has few uses. It can be alloyed with stainless steel to improve some of its mechanical properties and used as a doping agent in fiber optic cable where it can be used as an amplifier. One of ytterbium’s isotopes is being considered as a radiation source for portable X-ray machines.
What element family is ytterbium?
Ytterbium belongs to the lanthanide family. The lanthanides make up Row 6 of the periodic table. The periodic table is a chart that shows how the chemical elements are related to each other. The lanthanides are also known as the rare earth elements.
What things are made of ytterbium?
What is made of ytterbium?
What is ytterbium in the periodic table?
ytterbium (Yb), chemical element, a rare-earth metal of the lanthanide series of the periodic table.
How does ytterbium react with elements?
Ytterbium metal reacts with all the halogens to form ytterbium(III) halides. So, it reacts with fluorine, F2, chlorine, Cl2, bromine, I2, and iodine, I2, to form respectively ytterbium(III) bromide, YbF3, ytterbium(III) chloride, YbCl3, ytterbium(III) bromide, YbBr3, and ytterbium(III) iodide, YbI3.
What type of radiation does ytterbium-169 emit?
Ytterbium-169 in particular emits gamma rays. Gamma rays are similar to X-rays in that they pass through soft materials and tissues but are blocked by more dense materials such as bone.
When was pure ytterbium made?
In fact, the ytterbium studied by Marignac, Nilson, and Urbain was not pure ytterbium. Instead, it was combined with oxygen and other elements. Fairly pure ytterbium metal was not produced until 1937 and high purity ytterbium was not produced until 1953.
What is the oxidation state of YB in ytterbium?
Ytterbium is a chemical element with the symbol Yb and atomic number 70. It is the fourteenth and penultimate element in the lanthanide series, which is the basis of the relative stability of its +2 oxidation state. However, like the other lanthanides, its most common oxidation state is +3, as in its oxide, halides, and other compounds.
What family does ytterbium belong to?
Ytterbium belongs to the lanthanide family. The lanthanides make up Row 6 of the periodic table. The periodic table is a chart that shows how the chemical elements are related to each other. The lanthanides are also known as the rare earth elements.
